A TTORNEY FREDERICK M. TURCK AND BRUCE CLARK WHITE, OF NEW YORK, N. Y.

SHEET-DELIVERING DEVICE FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that we, FREDERICK M. TUROK and BRUCE C. WHITE, citizens ofthe United States, and residents of New York, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Sheet-Delivering Devices for Printing-Presses, of which the followingis a specification.

This invention relates to improvements in printing presses in whichsheets are fed to a sheet carrier, printed upon and finally released anddelivered, and particularly to such a type of printing press as is shownand described in Patent No. 1,146,039, dated July 13th, 1915, issued toFrederick M. Turck, and also shown and described in several of ourapplications for Letters Patent of even date herewith.

The object of our invention is to provide operative means for releasingonly such sheets as have received their final printing, and directingsuch released sheets away from the press.

Ainother object of our invention is to render the sheet releasing andsheet delivery mechanism inoperative upon unprinted or partially printedsheets as they pass the point of delivery.

The invention also includes certain details of construction hereinafterset forth.

In describing the invention in detail reference is had to theaccompanying drawings forming a part of this specification, wherein likecharacters of reference are used to designate corresponding partsthroughout the several views and in which:

Figure 1 is a general side elevation of a multi-color press to whichthis sheet delivery may be adapted. 2 is an enlarged side elevation ofthe delivery mechanism. Fig. 3 is a transverse section of same on line1, 1 of Fig. 5 showing the sheet grippers opened while the directingtapes are still in their normal or undeflected position. Fig. 4 issimilar to Fig. 3 except that the gri opening device or tumbler hasretired to its normal position while the sheet deflecting tapes areshown in a position to Specification of Letters Patent.

Fig. 6 is a plan iew of a part of thedelivery device. detail side elevation of the gripper opening mechanismshowing the parts from the opposite side of the press from that of Fig.2. Fig. 8 is a section of the same upon line 2, 2 of Fig. 7 Fig. 9 is asection through the tape-tension device on line 3, 3 of Fig. 10. Fig. 10is a sectional elevation of the same on line 4, 1 of Fig. 9. Fig. 11, isa horizontal section of the tape-tension adjustment on line 5, 5 of Fig.2. 7

Referring to Fig. 1, numeral 1 designates the bed-plate of the press,upon which are mounted the frames 2 and 3. In the latter are journaledthe two printing couples composed of the form or plate cylinders 4 and5, and the impression cylinders 6 and 7.

A power pulley 8 drives the cylinders through gearing, more fully shownand described in another of ourapplications, filed Aug. 29, 1917, SerialNumber 188,764, to

which reference is also made for more detailed descriptions of thesheet-feeding device sheet-carrier and sheet-grippers.

Means are provided at 9 and 10for inking the surface of theprinting-plates upon the cylinders 41 and 5 such means comprising theusual fountains 11, 12, 13 and 14, form rollers 15 and appropriatedistributing means.

For advancing the sheets to be printed upon, a sheet-carrier isprovided, composed of oppositely-disposed annular toothed carrier rings16, rigidly connected together by cross-braces 01' sheet-carriers 17.The carrier rings are geared to the cylinders 6 and 7 by gear rings 18.

In the machine herein shown a sheet is fed to one of the sheet-carriers17 for each revolution of the printing cylinders. Each cylinder hasthree divisions, each of which registers with a division or cross-brace17 of the sheet-carrier of which there are seven. Every thirdcross-brace or sheetcarrier 17 delivers a finished sheet at eachrevolution of the cylinder 6 and later re Fig. 7 is a ceives a freshsheet. preferably as follows:

Upon one end of cylinder 6 is formed a cam track 19 which is concentricfor the larger portion of its periphery. For the remaining portion thetrack is: extended radially by a gradual curve 20. This extended portionof the track 21 extends in a concentrio curve for a short distance,theiri'ecedes to the shorter radius at 22. See Fig. 4. Arch shapedframes 23 provide bearings for each end of the rock shaft 24 whichextends across the machine. To the-shaft 24 is keyed a cam arm 25.Clamped. into. the outer end of the latter by the bolt'26 is aroller-pin 27, upon which is journaled the cam-roller 28 which. ridesupon the cam track 19, 20, 21 and 22. To the shaft 24 are keyed two armsThis we accomplish 29 the upper ends of which form-journals 30 for across-shaft 31 upon which are mounted tape pulleys 32. Tape pulleys 33are secured. to the driving-shaft 34 which is mounted to runfreely inbearings 35 in the arch-framesi23.See .Figs. 3,4 and 6* A gear-wheel 36is keyed to the driving shaft 34, in position tomesh with one of theinternally toothed gear rings16, whereby; the tape pulleys .33 will bedriven in, the proper direction and at a peripheral speed corresponding,with the linear printing .speed of the sheetf Tapes 37 are trainedabout; the tape-pulleys32 and 33 and about the two tensionrollers 38 as,shown in Fig. 3. The rollers 38' are each provided with a shaft 39,

the projecting ends of which journal in bearings 40 formed in theheads41. The latter are secured and keyed to a tension-roller shaft 42which is j ournaled to rotate freely in bearings 43 the arch-frames 23.Rods 44 are pivotally connected, one to each'of the heads 41,'by meansof pins 45, rigidly secured thereto by nuts 46. Each of the rods 44 isfreeto: slide axially in the adjusting screw 47 which has screw-threadengagementwith the puppet 48. The latter is provid'ed with a roundshank49 which. is fitted" to turn freely in ahole in each arch-frame 23and is retained therein by the washer 50 and screw 51. A- compressionspring 52 encircles eachfrod 44 and thrusts against the head 53 thereofat one end and at its opposite endit thrusts against the end of theadjusting screw 47. By turning these screws the tension of the springsmay be altered as desired. The jam-nuts 54 on the screws .47 providemeans for locking the screwslin theirradjuste'd positions. Theoscillation of the puppets 48 is necessitated for the reason that thepins 45 describe an arc in moving from theposition shown in Fig. to thatshown in Fig. 4. Thetaction of the springs is such as totend to thrustthe heads 41 and rollers -.38 into .theposition shown in Fig. 3..anddraw thetapes .37 taut.

If the cam roller 28 be lifted by cam 20 and with it the arm 25, arms29, shaft 31 and pulleys 32 these parts will assume the position shownin Fig. 4, also shown in Fig- 6 in dotted lines. pulleys 32 and 33 isthereby increased but such increase is provided for by the turning ofthe rollers 38 and their heads 41 from the position of-Fig. 3 to that ofFig. 4,

against the thrust of springs 52 which are thereby compressed but whichinsure a tension on the tapes in whatever position the tape-pulleys 32may be moved. When the latter are in the position shown in Fig. 3 thetapes 37 will form a support for the sheet as it is carried forward anddownward toward the first printing couple 4 and 6. When the pulleys 32and tapes 37 arein theposition shown inFig. 4 the tapes still form asupport for the sheet which beingreleased from thegrippers in sheetcarriers 17 will be delivered upon the off-bearing tapes v55. Theselatter are trained about pulleys 56, mounted upon shaft 57 for whichbearings are provided in the archframes 23. The pulleys 56 arepreferably so spaced laterally that the pulleys 32 will be between themto form apractically continuous'tape sup p ort'for the sheet whendelivering. This is important for the reason that the sheet isuncontrolled from the instant the grippers 58 in the sheet-carrier .17release it-except for the tapes upon which it rests. These latter,running at a fixedspeed. at practicallyuastraight line tangent to thenormal sheet path form a delivery device in which .the sheet .isunaffected by frictional resistance or staticelectricity in its courseaway from the press.

The grippers 58 are secured to they grippershaft 59. This shaft extendsthrough the The distance between tape" gear-rings '16 in' W'hich'bearingsleeves are provided for it. These sleeves extend through the end wallsof the sheet-caITiers 17 forming dowels for accurately locating thesheet-carriers 17 between the rings 16. Screws further secure theringsto the sheet carriers. See Figs. 7 and 8. Keyed to each of theprojecting ends of each of the grippershafts 59 is a tumbler arm 60.T'eeth 61 are formed across the end of this arm as a short sector of aspur gear. 11 shoit sector of a spur pinion 62 meshes into the eeth ofarm 60. The pinion 62 is mounted to turn freely upon stud 63. The pinion62 is extended at a point opposite its teeth to form an arm, throughwhich passes a pin 64. This pin also passes through the end of a springrod 65, about which is coiled the compression tumbler-spring 66. againstthe puppet 67 in a manner to thrust the arms into the extreme angularposition after having been moved by the tumbler-pin This :springthrusts.

bler arm 60 is widened out by the inner projection or hump 68 and theouter projection or hump 69 of such form that when the parts are in theposition shown in Fig. 7 the inner hump 68 has come into contact withthe roller 71 upon the pin which latter is firmly secured by the nut 72in the upper end of the arm 7 3 of the tumbler-lever 74:. The lower arm7 5, the hub 76 and the upper arm 73 of the lever 7d are preferably madeintegral, the hub 7 6 is bored to turn freely upon the stud 7 7 whichlatter is secured firmly in the arch frame 23 by the nut 78 and Washer79. See Fig. 8. The arm 74 is retained upon the stud 77 by the nut 80and washer 81. At the lower end of the branch 7 5 of the lever 74 is aroller pin 82, firmly clamped to the arm 7 5 'by the clamp screw 83. Acam roller 84 similar to cam-roller 28 is arranged to roll upon the camtrack 19, 20, 21 and 22 and be lifted thereby for a short interval atevery rotation of the cylinder 6 whereby the roller 71 will act to openthe grippers of every third sheet. The cam-roller 84 as will be seenfrom Figs. 2, 3 and 4 which opens the grippers, acts in advance ofcam-roller 28 which changes the direction of the tapes 37. The cam 20,21, 22 is located upon the cylinder 6 in a position to deliver afinished sheet from that division of the sheet-carrier correspondingwith blank section of the cylinder 6 and its corresponding cylinder 4.The grippers 59 opened by the arm 74: will remain open until a freshsheet has been fed to them when they are closed as described in anotherapplication made by us of even date herewith.

The off-bearing tapes 55 are preferably driven at the same lineal speedas the tapes 37 and by mechanism not shown but preferably located at theouter end of said tapes.

The particular advantages of this form-of delivery are that it isadapted to a printingpress in which only certain sheets are to bedelivered while the intermediate sheets may continue in their course tothe printing units. This adapts it to a position between the feed andthe first printing. This is the only practical arrangement of printingcouples, feed and delivery. If the order is reversed and the deliveryoccurs between the final printing and the feed, a tangent delivery upontapes must be abandoned and for it must be substituted some form ofdelivery, in which the direction of the delivering sheet must bereversed about a drum or roller to get the sheet away. This reversingroller or other device contacts directly with freshly printed surface ofthe sheet and has the further disadvantage of turning the sheet up sidedown. A still further disadvantage of such an alternative arrangementlies in the fact that both the feed and delivery would be located at thesame end of the press, one

above the other, which is inconvenient for both. Another importantadvantage gained by the particular construction shown lies in the factthat the sheet is supported while delivering entirely by tapes runningin a horizontal direction at a tangent to their curved path and at aconstant speed thus spacing them accurately on the off-bearing belt.This simplifies their piling, interleaving or introduction into anotherpress for subsequent operations.

Vhile we have shown and described the preferred embodiment of theinvention, it will be obvious that various changes may be made asregards its form, detail construction and general arrangement withoutdeparting from the principle and scope of the invention.
